2010 DTM champion Paul di Resta admits he and his Mercedes team must improve following a difficult return for the Scot.

di Resta finished a disappointing 14th during Sunday's season opening race at the Hockenheimring after a three-year absence from the series.

The 28-year old reigned victorious during his last visit to the Hockenheimring, beating Audi's outgoing champion Timo Scheider on the way to his title winning success.

But di Resta has joined a Mercedes squad currently enduring one of their worst run of DTM form in recent history with the Stuttgart manufacturer failing to score a single point at the season opener.

Pascal Wehrlein was their highest placed driver in eleventh position but finished a staggering 20 seconds off even scoring a single point.

The former Force India star says despite his team's woeful start he has every confidence that they can reverse their current situation.

"That was a very difficult race for me. I'm going to have to up my game in order to slot back into the DTM on a par with my team-mates," di Resta admitted.

"More importantly, however, we need to improve as manufacturers. We've now got two weeks in which to recover and then make the best of it.

"We're somewhat down compared to BMW and Audi, but I have absolute confidence in the team that we will strike back and I hope that we can succeed soon."
